Maire-Ilon Wikland (née Pääbo; born 5 February 1930) is an Estonian-born Swedish artist and illustrator. Wikland was born in Tartu, Estonia and raised in Haapsalu, Lääne County on Estonia's Baltic coast. In 1944 she escaped with the family of a classmate from the second Soviet occupation of Estonia, to Sweden, where she arrived as a refugee. In 1953 Wikland applied for a job as illustrator at Rabén & Sjögren. She was met by Astrid Lindgren, who had just finished writing the book Mio, my Son and who could see immediately that Wikland was able to "draw fairytales".
